Can anyone tell me if there is a way to universally change the function # of days in the course preferences after a build has been imported without having to go in and unlock each course section first?
If you are asking how to mass update the course preference for frequency, you can do that using the Auto-Fill Course Information function which is in PowerScheduler under Functions. You can use the update selection function to hand select courses to work with when using Auto-Fill course info.
However, updating the course preference won't alter the expression on the sections you have imported. To have sections build according to the updated frequency you would have to run/import a brand new build.
Thanks so much for your help!
